And as time went on, still a new note crept into his letters; the first admiration for France was strengthened and almost replaced by a new feeling--a profound conviction that France and the French people were fighting the fight of liberty against enormous odds. The new spirit of France--the spirit of the "Marseillaise," strengthened by a grim determination and absolute certainty of being right--pervades every line he writes. So he gave up the ambulance service and enlisted in the French flying corps along with an ever-increasing number of other Americans. The spirit which pervades them is something above the spirit of adventure that draws many to war; it is the spirit of a man who has found an inspiring duty toward the advancement of liberty and humanity and is glad and proud to contribute what he can. His last letters bring out a new point--the assurance of victory of a just cause. "Of late," he writes, "things are much brighter and one can feel a certain elation in the air. Victory, before, was a sort of academic certainty; now, it is felt." F. C. P. November 10, 1916. FLYING FOR FRANCE CHAPTER I VERDUN Beneath the canvas of a huge hangar mechanicians are at work on the motor of an airplane. Outside, on the borders of an aviation field, others loiter awaiting their aërial charge's return from the sky. Near the hangar stands a hut-shaped tent. In front of it several short-winged biplanes are lined up; inside it three or four young men are lolling in wicker chairs. They wear the uniform of French army aviators. These uniforms, and the grim-looking machine guns mounted on the upper planes of the little aircraft, are the only warlike note in a pleasantly peaceful scene. The war seems very remote. It is hard to believe that the greatest of all battles--Verdun--rages only twenty-five miles to the north, and that the field and hangars and mechanicians and aviators and airplanes are all playing a part therein. Suddenly there is the distant hum of a motor. One of the pilots emerges from the tent and gazes fixedly up into the blue sky. He points, and one glimpses a black speck against the blue, high overhead. The sound of the motor ceases, and the speck grows larger. It moves earthward in steep dives and circles, and as it swoops closer, takes on the shape of an airplane. Now one can make out the red, white, and blue circles under the wings which mark a French war-plane, and the distinctive insignia of the pilot on its sides. "_Ton patron arrive!_" one mechanician cries to another. "Your boss is coming!"
